PATRIK ANDERSSON, OF NEW YORK, N. Y.

PHOTOGRAPH-PRINTING MACHINE.

Application filed October 12, 1921. Serial No. 507,244.

To all whom t may concern.'

Be it known that I, PATRIK ANDEnssoN, a citizen of Sweden, and aresident oi: the city oi New York, borough oi' Manhattan, in the countyand State oft New York, have invented a new and ImprovedPhotograph-Printing Machine, o'l' which the following as a full, clear,and exact description.

This invention relates to photograph printing machines and has for anobject to provide a machine in which the time of cycle of printingoperation is decreased to a minimum.

Another object of the invention is to provide a photographers printingmachine which is especially designed to decrease the time of cycle ofprinting operation without diminishing the various adjustments requiredby' professional photographers.

A still further object of the invention is to provide a photographprinting machine wherein the print when complete is dischargedsubstantially simultaneously with the application of a new sensitizedsheet.

In the accompanying drawings- Figure 1 is a side view of a machinedisclosing one embodiment of the invention, the same being shown openand ready to receive the print paper. y

Figure 2 is a front view oit' the structure shown in Figure 1.

Figure 3 is a sectional view through Figure 4 approximately on line 3 3.

Figure 4 is a sectional view through Figure 3 on line 4-4, the sameillustrating substantially a front view of the frame and associatedparts shown in Figure 2.

Referring to the accompanying drawings by numeral, 1 indicates a frameor support which may be of any desired material and which acts tosupport a box 2 formed of any suitable material. This box is shown as arectangular box positioned at an angle so that the operator may morereadily place the print paper in position. A foot pedal 3 is providednear the bottom of the frame 1 and connected to a rock shaft 4 whichwhen rocked, will swing the arm 5 rigidly secured thereto, said arm inturn being pivotally connected with a link 6 pivotally connected at 7 toa fitting 8 secured to the arm 9. The

' arm 9 is pivotally connected at 10 to the frame 1 and carries fittings11 and 12 for pivotally connecting the links 13 and 14 to arm 9. Link 13is pivotally connected at`15 with the fitting 16 secured to the arm 17car# rying an extension 18 on which a lifter 19 is pivotally mounted andheld in a given position by suitable spring 20.

Then the extension 18 is swung upwardly as arm 17 is swung downwardly,lifter 19 strikes against the projection 21 so as to be swung slightlyand thereby move out of the path of the lever 22. Before the lifter 19has been moved out of engagement with the lever 22, said lever is swungon its pivotal supporting rod 23 and has rocked through the arm 24 theshaft 24 sufficiently to move the stop 25 out of the path of movement ofthe print 26 whereby said print may be slid downwardly into the box orreceptacle 27.

It will be noted that the shaft 24 carrying the stop or door 25 ispivotally mounted in suitable journals secured to the frame 28, whichframe is slidable along the side angle bars 29 and 30. These angle barsand associated parts are identical so that a description of one willapply to both. The frame 28 carries a lug 31 having an overhangingshoulder 32 as shown in Figure 4 which partially encircles the angle bar29 so as to hold the parts together. The angle bar 29 extends from thefront of the machine to the rear and is journaled on the shaft 23 sothat the frame 28 may be readily swung upwardly whenever desired. Ashort angle piece 33 is secured to the frame 28 above the lug 31 andcarries a spring 34 acting against the end 35 of the pivotally mountedbrake 36, which brake normally bears against one face of the angle bar29 and, consequently, frictionally locks the frame 28 in any adjustedposition.

By this construction and arrangement, the angle bar 29 may be slidreadily toward and from the rear of the machine and may be swungupwardly at any time. The frame 28 is provided with a longitudinal slot37 through which the clamping bolts 38 and 39 extend, said bolts actingto clamp the centering arms 40 and 41 in any desired adjusted positionalong the frame 28. These arms are provided with side covering plates 42and 43 which cover that part of the glass 44 carried by the box 2 whichis Inot exposed between the arms 4() and 41. Co-acting with the arms 40and 41 is a negative holding plate 45 having a central notch 46 and aplurality of side notches 47 arranged in regular stepped order forreceiving negatives of diii'erent sizes. The construction is provided toreceive glass negatives and after the negative has been properlypositioned in one ofthe notches of plate 45, members and4i are movedslightly over the edges of the negative and then the bolts 38 and 39 aretightened. The negative and the paperguiding members 40i and 4l arethenin position for receiving` print paper. A pressure pad 48 isprovided which is ormedivitha suitable sott face for pressing againstthe paper and witha back off anykind, said back being. provided withastrap or Asleeve49,l adapted to slide over the. armv rigidlyseeured vto`shat 5l by ,a set screw or other suitable means. A spring hook 52ispositioned .as

'i .shown in Figurel to snap.l over the sleeve 49j,andtherebyloclrthejpad 48 in place. rThese `pads yare,removable thatonemay be proyvided oi kproper size to fit between the yarms 40 and 4lwhen pedal-has been dei pressed. A member 53 is rigidly secured tos'yhaiit 51 and'isy acted upon by -a retractable lspring54fornormally'holding the parts as lshown in Figure l. YA n ,armfyis Valsovrigidly secured to shaitt landis ypivotally finountedatlt tothe linkl4ivhereby Whenever pedal 3 is depressed, these: members will be moved`for swingingthe ,pads-8 down- Vivardly and againstl 'the print paperplaced on the negative supported onthe glass plateV 7 and by the plate45. As soon as the pedal Bis released,: spring 54 Willmove the parts`back again quickly to theposition shown `in Allligure 4 and saidmovement ,-ivill cause the `litter 19 toberaised andthereby swing the,lever Y22 upwardly sufficient distance tto move the stop 25 a.ysuflicient. distance to allow the printedpaper to automatically slidedown into the receptacle 27 lor in case it should litail to moveautomatically,lthe operator may givethe same `a slightpush as `heplacesfthe fnext vprintpaper in position. .ln this Way tbereis no lossot time inapplying ander:- posing the print paper andalso by reason. ofthe adjustment of they arms 4() and.4l,the use of plate and,associatedparts, there is a minimum loss of time in adjusting the partsto .receive .derent sized negatives;
